Description
FIELD OF THE INVENTION
The present invention is directed to a folder for receiving
papers.
BACKGROUND OF THE INVENTION
Folders are often used by students, professionals, and others to
store loose leaf papers, hand-outs, pamphlets, and other items.
However, most existing folders can receive only limited amounts of
papers and other items before the sides of the folders tend to pull
away and rip from the body of the folder. Many existing folders
also often include a set of holes formed in the body of the folder
to attach the folder to a binder, such as a standard three ring
binder. However, when the folder is mounted in a binder, the papers
received in the folder may contact the binder rings, which can
crush or wrinkle the items in the folder. Furthermore, the binder
rings can pull or rip through the holes in the folder. Accordingly,
there is a need for a folder that is expandable to receive large
volumes of paper. There is also a need for a folder that can be
mounted to a binder such that the items received in the folder are
not damaged by the binder, and that resists tearing by the rings of
the binder.
SUMMARY OF THE INVENTION
In one embodiment, the invention is a folder that can expand to
receive large volumes of paper. In particular, the pockets of the
folder includes expansions panels which allow the pockets to
expand. The corners of the pockets may include notches to increase
the expansion capability of the binder pockets. The folder may also
include a spine that extends from a rear surface of the folder. The
spine includes a set of binder-receiving holes such that the
interior of the folder is isolated from the rings of the binder.
The spine is preferably reinforced to resist tearing forces
imparted by the rings of the binder.
In a preferred embodiment, the invention is a folder for receiving
papers including a first side panel including a recess formed in an
edge thereof, and a first lower panel facing the side panel. The
first side panel and the first lower panel are joined to form a
pocket therebetween, and the recess is located adjacent an open end
of the pocket to enable the pocket to expand without tearing the
first side panel.
Other objects and advantages of the present invention will be
apparent from the following description and the accompanying
drawings.

DETAILED DESCRIPTION
As shown in FIG. 2, in one embodiment the invention is a folder 10
having a pair of opposed, attached side panels 12, 14 separated by
a center fold line 16. Side panel 12 forms a front panel of the
folder 10, and side panel 14 forms a back panel of the folder 10.
The folder 10 includes a pair of lower panels 18, 20, that each
face a respective side panel 12, 14. The lower panel 18 and side
panel 12 form a pocket 22 for receiving papers and other loose
items. Similarly, the lower panel 20 and side panel 14 form a
pocket 24 between the lower panel 20 and the side panel 14. Each
lower panel 18, 20 each includes a tapered inner surface 26, 28 to
facilitate sliding papers under the lower panels 18, 20 in a
lateral direction. As shown in FIG. 6, each side panel 12, 14 may
include a flap 33 extending from its upper edge to help retain
papers in the pockets 22, 24. The flaps 33 also help to protect the
edges of the papers received in the pockets 22, 24. The flaps 33
may also be used to sort papers received in the pockets 22, 24, for
example by separating the papers in each pocket into two stacks
(one stack located above a flap 33, and the other located below a
flap 33). The flaps 33 may be located at a variety of positions and
take a variety of shapes beyond those illustrated herein.
Returning to FIG. 2, each side panel 12, 14 includes a top
reinforcing strip 30, side reinforcing strip 32, and a pocket
reinforcing strip 34 to increase the strength of the folder 10. As
shown in FIG. 4, the pocket reinforcing strip 34 includes an inner
38, middle 40, and outer 42 fold line. The fold lines 38, 40, 42
define a first expansion panel 44 and a second expansion panel 46.
As will be discussed in greater detail below, in order to form the
folder 10 from the blank 50 shown in FIG. 4, the lower panels 18,
20 are folded about the fold lines 52, 54 until they lie against
their respective side panels 12, 14. Each pocket reinforcing strip
34 is then folded about its middle fold line 40, and the pocket
reinforcing strip 34 is then glued to its respective lower panel
18, 20. The outer fold line 42 and the second expansion panel 46
are located on the outer surface of the folder (see FIG. 1), and
the inner fold line 38 and the second expansion panel 44 are
located on the inner surface of the folder (see FIG. 2).
Returning to FIG. 2, each side panel 12, 14 also includes an
inwardly-extending notch, or recess 60, located on the outer edge
of the side panels 12, 14 and at the top edge of each lower panel
18, 20. The notch 60 is located adjacent the open end of the
pockets 22, 24 and is preferably generally shaped as a sideways
"U". The notch 60 may extend inwardly to a depth such that its
inner point A is roughly aligned with the inner fold line 38 (see
FIG. 2) and the outer fold line 42 (see FIG. 1) of each lower panel
18, 20. Thus, the upper edge of the pocket reinforcing strip 34
preferably forms the lower edge of the notches 60. The notches 60
and expansion panels 44, 46 on each side of the folder 10 cooperate
to provide an expandable pocket. When one or both of the pockets
22, 24 are filled with paper, the lower panels 18, 20 are pulled
away from their respective side panels 12, 14. This also pulls the
expansion panels 44, 46 away from the side panels 12, 14 (i.e. such
that the expansion panels 44, 46 are not parallel to the plane of
the associated side panel). The expansion panels 44, 46 also move
away from each other (i.e. each pivots about the middle fold line
40) when the pockets 22, 24 are expanded.
The notch 60 is preferably located at the upper end or free edge 61
of the side edge 63 of a lower panel 18, 20, although the notch 60
may have other locations. The notches 60 enables the lower panels
18, 20 to pull away from the respective side panels 12, 14 while
reducing the propensity of the side panels 12, 14 to tear.
When the pockets 22, 24 are filled to their maximum capacity, the
expansion panels 44, 46 may be in a nearly vertical position when
the folder 10 is laid flat against on a surface; that is, the
expansion panels 44, 46 may be located in a plane that is generally
perpendicular to the plane of its respective side panel. For
example, FIG. 3 illustrates a side view of the folder 10 when one
of the pockets 22 of the folder 10 is filled with a plurality of
papers 64. In this state, the expansion panels 44, 46 are each in a
nearly vertical orientation. When the expansion panels 44, 46 are
pulled into this position, the pocket 22 has a greater volume, and
in this manner the expansion panels 44, 46 increase the capacity of
the folder 10.
As shown in FIG. 2, each side panel 12, 14 also includes an inner
fold line 68 located adjacent the center fold line 16. The inner
fold lines 68 and center fold line 16 define a pair of inner
expansion panels 70. When the pockets 22, 24 are filled with papers
64 as shown in FIG. 3, the inner expansion pockets 70 may shift out
of the plane of their respective side panels 12, 14.
When the pockets 22, 24 of the folder 10 are filled, the inner
expansion panels 70 may be nearly perpendicular to the plane of the
side panels 12, 14 when the folder 10 is in a closed position (i.e.
the expansion panels 70 are located in an almost vertical
position).
The inner fold lines 68 are generally perforated along their length
to provide increased expansion capabilities. However, as shown in
FIG. 1, the inner fold lines 68 are preferably not perforated at
those portions of the fold lines 68 located adjacent the holes 72
in the spine 74. The portions of the inner fold lines 68 adjacent
the holes 72 are preferably scored but not perforated to increase
the strength of the folder 10 adjacent the holes 72. Additional
inner fold lines (not shown) forming additional inner expansion
panels may be added to the folder 10, as desired in order to
increase the capacity of the folder 10.
As shown in FIG. 4, a blank 50 may be used in a preferred method
for forming the folder 10 of the present invention. In order to
form the folder I 0 from the blank 50, the lower panels 18, 20 are
folded about their fold lines 52, 54 until each lower panel 18, 20
lies against its respective side panel 12, 14. The top reinforcing
strips 30 are folded inwardly about their fold lines 76, the side
reinforcing strips 32 are folded inwardly about their fold lines
78, and the pocket reinforcing strips 34 are folded inwardly about
their center fold lines 40. The top 30 and side 32 reinforcing
strips are then adhered to their respective side panels 12, 14. The
pocket reinforcing strips 34 are adhered to their respective lower
panels 18, 20.
The blank 50 includes a pair of notch cutouts 80, each notch
cut-out 80 including a generally oval-shaped head portion 82 and a
neck portion 84. After the side reinforcing strips 32 and pocket
reinforcing strips 34 are folded about their respective fold lines
78, 40, the head portions 82 forms the notches 60 in each side
panel 12, 14. Each head portion 82 includes a small "V" shaped
notch 86 to help guide the folding of the side reinforcing strips
32 about their fold lines 78. The flange portion 88 of the side
reinforcing strips 32 provide reinforcing about the notches 60 to
help reduce tearing of the notches (in particular, the inner
portions A of the notches 60 are reinforced by the flange portions
88, see FIG. 2).
Although illustrated in conjunction with a two-pocket folder, the
notch 60 and expansion panels 44, 46, 70 of the present invention
may be used in any folder having a pocket, including folders having
a single panel and single pocket. Furthermore, the expansion panels
44, 46 need not necessarily be defined by score lines. That is, if
the score lines 38, 42, were not included in the folder 10, the
pockets 22, 24 would still be expandable due to the presence of the
notches 60. The score lines 38, 42 merely provide a guide for the
expansion of the pockets 22, 24. Thus, the term "expansion panel"
(also termed an "expansion portion) includes those portions of the
folder that can shift to a position out of the plane of the side
panels 12, 14, whether such "panel" is defined by a score line or
not.
Returning to FIG. 4, the blank 50 also includes a pair of spine
portions 90, 92 separated by a spine fold line 94. Each spine
portion 90, 92 includes a set of corresponding holes 72a, 72b. The
spine portions 90, 92 are folded toward each other about the spine
fold line 94 until they are interfacially aligned. The spin
portions 90, 92 are then adhered together to form the spine 74. The
set of holes 72a are aligned with the set of holes 72b to form the
holes 72 (FIG. 1). After the spine portions 90, 92 are pulled
together, the outer spine fold lines 96 are pulled together to form
the center fold line 16 shown in FIG. 2. Each outer spine fold line
96 preferably has the same pattern of perforations and scoring as
the inner fold lines 70, although this pattern is not visible in
the center fold line 16 in FIG. 2. As shown in FIG. 1, the spine 74
extends rearwardly from the body of the folder 10. A binder, such
as a three ring binder (not shown), can be passed through the holes
72 in the spine 74 to attach the folder 10 to the binder. The holes
72 formed in the spine 74 are preferably generally oval or
elliptical shaped to make it easier to attach the folder 10 to a
binder.
An advantage provided under the present invention is that when the
folder 10 is attached to a binder, the binding mechanism does not
pass through the side panels 12, 14 of the folder, but instead
passes only through the spine 74. Thus, when the binder rings are
passed through the spine 74, the binder rings are isolated from the
contents received in the pockets 22, 24 of the folder 10, and
therefore the binder does not contact or interfere with the
contents of the folder. Furthermore, the spine 74 is made of
two-ply material (the spine portions 90, 92), and therefore the
spine 74 is reinforced to prevent the binder rings from pulling
through holes 72 of the spine 74. The spine 74 may be further
reinforced as desired. However, it should be understood that nearly
any method of forming a spine located remotely from the internal
pockets of a folder may be used without departing from the scope of
the present invention. Thus, the spine 74 may be single ply, may be
formed of different materials than the rest of the folder 10, may
formed by attaching the spine to a pre-formed folder, or may be
formed by other methods. As shown in FIG. 1, the spine 74
preferably has chamfered outer corners 98 to reduce interference
between the spine 98 and the binding mechanism of the binder.
The blank 50 and folder 10 are preferably made of sheet like
material that is generally rigid yet includes some flexibility,
including but not limited to cardboard, plastic, cloth and the
like.
Another embodiment of the invention is shown in FIG. 5, wherein the
folder 10' includes only a single side panel 12 and a single lower
panel 18. The folder 10' includes a cover panel 100 to help retain
papers in the folder 10'. The cover panel 100 normally lies flat
against the side panel 12 and lower panel 18, but can pulled from
the side panel 12 and lower panel 18 to fit papers into the pocket
22. The cover panel 100 includes a plurality of fold lines 102
having perforated and scored portions which enable the cover panel
to be folded over papers received in the folder 10'. The portions
of the folder 10' adjacent the holes 72 are reinforced by the
presence of the cover panel 100. If the cover panel 100 is not used
on the folder 10', the areas adjacent the holes 72 are preferably
reinforced with an extra ply of material.
The folder 10' of FIG. 5 also includes a pair of label slots 104
adjacent the outer edge of the side panel 12. The slots 104 are
shaped and located to receive a pair of feet 106 of a label tag
108. The label tag 108 is a well known mechanism in the art, and
typically is used to label folders that are received in filing
cabinets. A label tag 108 typically includes a two-ply piece of
generally transparent material. A piece of paper 109 with indicia
thereon can be inserted between the two plys of the label tag 108
to identify the contents of the folder 10'. In this manner, when a
plurality of folders are received in a binder, each folder can be
easily identified by its label tag 108. A plurality of slots 104
(not shown) may be located along the outer, upper or lower edges of
the side panel 12 such that a label tag 108 can be located at
nearly any location along the outer edges of the side panel. The
folder 10' may also include a tab 110 that is integrally formed
with an outer edge of the folder.
Having described the invention in detail and by reference to the
preferred embodiments, it will be apparent that modifications and
variations thereof are possible without departing from the scope of
the invention.
